$|$Assignment: Project Scheduling and Risk Analysis Using PERT Exercise $1$ Over $10$ periods your estimate and actual budgets are presented below. You are trying to determine whether the error in your estimates is a random error or a systematic error. Use tracking signal to calculate a measure of your bias in cost estimation. Exercise $2$ You are managing the development of $18$ instructional chapters for a new training program. The first chapter requires $21$ hours to complete, and the development team follows a learning curve with a learning rate of $\backslash (78\backslash \%\backslash ).$ The hourly labor rate is $\backslash (\backslash$$ $65\backslash ),$ and an overhead rate of $\backslash (20\backslash \%\backslash )$ is applied to direct labor costs. a$.$ Calculate the expected development time for each chapter $($Chapters $1$ through $18),$ considering the learning curve effect. b$.$ Calculate the cumulative development time after completing all $18$ chapters. c$.$ Determine the cost of developing each chapter and the cumulative cost after all $18$ chapters are developed.
